Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are important safety parameters. In this project, we are going to build a Simple Smoke Detector Circuit without using any Microcontroller. This circuit triggers the Buzzer whenever it detects Smoke or fire nearby. This circuit mainly uses the MQ6 Smoke/Gas sensor to…
Coil Gun, as many people think (including me) is not just a fun toy with a tube and few coils around it which can shoot projectiles to a certain distance. Scientists at Sandia National Laboratories believe that a coilgun can be engineered to accelerate particles at a greater speed that is high enough to escape earth’s gravity. Yes, you heard that right! Coil gun could…
GPS stands for Global Positioning System and it is used to find out location, altitude, speed, date and time in UTC. In this project we are going to interface a GPS module with NodeMCU. A simple local web server is created using NodeMCU and the location details are updated in that server webpage. Specialty of this IoT based project is we can check the location in Goolge Maps…
Stepper motors is a brushless DC motor that rotates in discrete steps, and are the best choice for many precision motion control applications. Also, stepper motors are good for positioning, speed control and applications which require high torque at low speed.
In previous tutorials of MATLAB, we have explained that how to use MATLAB to control DC…
Raspberry Pi is an ARM cortex based popular development board designed for Electronic Engineers and Hobbyists. With the processing speed and memory, Raspberry Pi can be used for performing different functions at a time, like a normal PC, and hence it is called Mini Computer in your palm. We have created a series of Raspberry Pi tutorials, to start with Raspberry Pi from…
Power amplifier is the part of sound electronics. It is designed to maximize the magnitude of the power of given input signal. In sound electronics, the operational amplifier increases the voltage of the signal, but unable to provide the current, which is required to drive a load. In this tutorial, we will build a 40W Amplifier using TDA2040 Power Amplifier IC and two Power…
In this tutorial we are going to discuss and design a circuit for measuring distance. This circuit is developed by interfacing ultrasonic sensor“HC-SR04” with AVR microcontroller. This sensor uses a technique called “ECHO” which is something you get when sound reflects back after striking with a surface.
We know that…
We all want our home appliances to be controlled automatically based on some conditions and that's called Home automation. Today we are going to control the light based of darkness outside, the light turns ON automatically when it is dark outside and turns off when it gets bright. For this, we need a light sensor to detect the light condition and some circuitry to control…
Infrared is the most commonly used wireless data transfer medium for limited range, and we already covered about simple IR Transmitter and Receiver circuit. Today in this Article, we will learn how to build a Crude Wireless Audio Transfer Circuit Using IR LEDs. Using this circuit you should be able to play songs from your IPod, mobile or computer to an external speaker…
In this project we are going to design a 25V range digital voltmeter by using ATMEGA32A microcontroller. In ATMEGA, we are going to use 10bit ADC (Analog to Digital Converter) to build a digital voltmeter. Now the ADC in ATMEGA can not take a input more than +5V, so for getting a higher range we are going to use a voltage divider circuit.

There are various circuits or methods available for building Switched Mode Power Supply (SMPS). SMPS is used for generating controlled and isolated DC voltage from unregulated DC power source. Forward converter circuit is similar to the fly-back converter circuit but it is more efficient than fly-back converter circuit. Forward converter is mainly used for the application…
Stepper motor is brushless DC motor, which can be rotated in small angles, these angles are called steps. Generally stepper motor use 200 steps to complete 360 degree rotation, means its rotate 1.8 degree per step. Stepper motor is used in many devices which needs precise rotational movement like robots, antennas, hard drives etc. We can rotate stepper motor to any…
